Switching from freezer to fridge long-term isn't really an option; it would cause too much marital discord.May be preserve the samples compromised by the storm and keep them in the refrigerator instead of the freezer. Or put them back at freezing temperatures and just reccord that they spent some time at room temperature. I expect that over the years I'll be tending my stash there will be power outages or other reasons why my nic is not at freezing temperatures at all times.
